SLE patients exhibit a higher percentage of effector CD4+ T cells. (A) A representative pair of age, sex, and ethnicity matched SLE patient and the corresponding healthy control. T cells were stained for CD3, CD4, CD45RA, and CCR7 to define naive, central memory (CM), and effector memory (EM) CD4+ T cells. (B) Frequency of EM CD4+ T cells in total CD4+ T cells from SLE patients (SLEDAI: 4–8) and controls.
